がある。2. Description of the Related Art Generally, in the case of a heat pump type air conditioner, the capacity of an indoor unit changes according to the outside air temperature. For example, in the case of cooling, when the outside air temperature is high, the condensation capacity of the outdoor unit is reduced, so that the cooling capacity is reduced in midsummer when cooling is most desired. In spring or autumn, the compressor may stop immediately after the capacity is too high, or the heat exchanger of the indoor unit may freeze. In addition, in the case of heating, when the outdoor temperature is high, the evaporating capacity of the outdoor unit increases, so the capacity is too high in spring or autumn and the compressor stops immediately or the discharge pressure of the compressor increases and shortens the life of the compressor. There is. Conversely, when the outside air temperature is low, the evaporation capacity is reduced, so that the heating capacity may be reduced in the midwinter when it is desired to heat the most.

・暖房能力に制御するというものが知られている。In the conventional outside air temperature control of an air conditioner, in order to solve the above-described problem, an outside air temperature sensor provided in an outdoor unit detects the outside air temperature, and the air temperature is controlled according to the detected outside air temperature. It is known that the capacity of the outdoor unit is controlled by regulating the maximum operating frequency and the minimum operating frequency of the compressor as shown in FIG. 8 to control the refrigeration cycle or the cooling / heating capacity appropriately.

ことがあった。However, in the case of a so-called multi-type air conditioner in which the air conditioner can connect a plurality of indoor units, since the number of operating indoor units and the connection capacity type are various, conventional air conditioners are not suitable. In a method that regulates the maximum operating frequency and the minimum operating frequency such as the outside air temperature control of an air conditioner, if the number of operating units is small or the connection capacity type is small, the maximum operating frequency is not regulated and the number of operating units is large. When the connection capacity type was large, the minimum operation frequency regulation was not sometimes applied.

It is an object of the present invention to regulate the operating frequency of an indoor unit, always maintain an appropriate refrigeration cycle even when the outside air temperature changes, and suppress a change in the capacity of the indoor unit due to a change in the outside air temperature.

In the case of the cooling operation, when the outside air temperature is high, the condensation capacity of the outdoor unit is reduced, and the cooling capacity is reduced. Therefore, when the outside air temperature is high, the operating frequency of the compressor is increased by a predetermined amount by adding a predetermined value to the instruction frequency, and the cooling capacity of the indoor unit is increased by increasing the refrigerant circulation amount. In the case of the heating operation, when the outside air temperature is low, the evaporation capacity of the outdoor unit is reduced, and the heating capacity is reduced. Therefore, when the outside air temperature is low, the operating frequency of the compressor is increased by a predetermined amount by adding a constant value to the instruction frequency, and the heating capacity of the indoor unit is increased by increasing the refrigerant circulation amount. By the above operation, the minimum frequency can be reliably regulated in all the operating states.

る。According to a second aspect of the present invention, the predetermined value is reduced to the designated frequency according to the outside air temperature. In the case of the cooling operation, when the outside air temperature is low, the condensation capacity of the outdoor unit increases and the cooling capacity increases. Therefore, when the outside air temperature is low, the operating frequency of the compressor is decreased by a predetermined amount by reducing the instruction frequency by a predetermined value, and the cooling capacity of the indoor unit is decreased by reducing the refrigerant circulation amount. In the heating operation, when the outside air temperature is high, the evaporation capacity of the outdoor unit increases, and the heating capacity increases. Therefore, when the outside air temperature is high, the operating frequency of the compressor is decreased by a predetermined amount by decreasing the instruction frequency by a predetermined value, and the heating capacity of the indoor unit is decreased by reducing the refrigerant circulation amount. By the above operation, the maximum frequency can be reliably regulated in all the operating states.

ができる。According to a third aspect of the present invention, the specified frequency is multiplied by a predetermined value according to the outside air temperature. When the required capacity level sent from the indoor unit is high, that is, when the outdoor unit is operating at high power, the capacity change amount of the outdoor unit that changes according to the outside temperature is large, so the capacity change amount of the indoor unit Also increases. On the other hand, when the required capacity level sent from the indoor unit is low, the capacity change amount of the outdoor unit that changes according to the outside air temperature is small, so that the capacity change amount of the indoor unit is also small. Therefore, by multiplying the designated frequency determined according to the required capacity level sent from the indoor unit by a predetermined value, when the required capacity level is large, the amount of increase or decrease of the operating frequency of the compressor is increased, and conversely, the required capacity is increased. When the level is small, the amount of increase or decrease in the operating frequency of the compressor can be reduced. By the above-described operation, the capacity change amount that changes according to the operation state of the outdoor unit can be corrected, and the maximum frequency regulation or the minimum frequency regulation can be reliably performed in all the operation states.

ることができる。According to a fourth aspect of the present invention, a value to be added to or subtracted from or multiplied by the indicated frequency is changed in accordance with the outside air temperature. When the outside air temperature is extremely high or low, the capacity of the outdoor unit also becomes extremely large or low. Therefore, by increasing or decreasing the indicated frequency according to the outside air temperature, if the outside air temperature is extremely high or low, the operating frequency of the compressor is increased or decreased, and conversely, the outside air temperature is slightly increased. If it is lower or higher, the amount of increase or decrease in the operating frequency of the compressor can be reduced.
With the above-described operation, the capacity change amount that changes according to the change amount of the outside air temperature can be corrected, and the maximum frequency regulation and the minimum frequency regulation can be reliably performed in all the operation states.

According to Nos. 4 to 4, the operating frequency of the compressor is reliably regulated in both the single type air conditioner and the air conditioner in which the number of operating units and the connection capacity type change, such as a multi-type air conditioner. Refrigeration cycle is always maintained even if the temperature changes, and a change in the performance of the indoor unit due to a change in the outside air temperature can be suppressed. In addition, by raising the operating frequency of the compressor in accordance with the outside air temperature, an immediate warming / cooling effect can be brought about, and the user can be provided with a comfortable feeling. In addition, by lowering the operating frequency of the compressor by the outside air temperature, it is possible to prevent the temperature of the evaporator from lowering during cooling and prevent the evaporator from freezing, and also to prevent the discharge pressure from increasing during heating and prolong the life of the compressor. . At the same time, reducing the capacity when the room temperature is close to the set temperature can reduce the number of compressor shutdowns,
Power consumption can be reduced.
